$y \geq \frac{1}{2} x - 3$

Step 1

Rewrite so $x$ is on the left side of the inequality.

$\frac{1}{2} x - 3 \leq y$

Step 2

Combine $\frac{1}{2}$ and $x$ .

$\frac{x}{2} - 3 \leq y$

Step 3

Add $3$ to both sides of the inequality.

$\frac{x}{2} \leq y + 3$

Step 4

Multiply both sides by $2$ .

$\frac{x}{2} \cdot 2 \leq (y + 3) \cdot 2$

Step 5.1.1.1

Cancel the common factor.

$\frac{x}{2} \cdot 2 \leq (y + 3) \cdot 2$

Step 5.1.1.2

Rewrite the expression.

$x \leq (y + 3) \cdot 2$

$x \leq (y + 3) \cdot 2$

$x \leq (y + 3) \cdot 2$

Step 5.2.1.2.1

Move $2$ to the left of $y$ .

$x \leq 2 \cdot y + 3 \cdot 2$

Step 5.2.1.2.2

Multiply $3$ by $2$ .

$x \leq 2 y + 6$

$x \leq 2 y + 6$

$x \leq 2 y + 6$

$x \leq 2 y + 6$

$x \leq 2 y + 6$
